Moving to fibre extra from basic fibre

Due a somewhat convoluted order (fibre extra, changed to BB, back to fibre again) I'm currently on 40 down profile and should be on extra (80/20). Just for peace of mind, I've been told that the switch to fibre extra needs an engineer call to the cabinet to move to a faster port. Is this correct and it's not a software control at PN/BT side?
